EverGreenCoin (EGC) is a decentralised, open-source cryptocurrency forked from Bitcoin and inaugurated in December 2015. It started life as a proof-of-work (PoW) coin using the X15 spectrum of hashing algorithms for generating coins, but it was converted into a pure proof-of-stake (PoS) currency some six month after its launch. It offers a 7% annual interest on staked coins. EverGreenCoin's parameters make it a faster and more environmentally-friendly cryptocurrency than Bitcoin. Initial announcement.

BitKey is a FREE, Debian-based live Linux distribution designed for Bitcoin users; it comes with specialist utilities to perform highly secure air-gapped Bitcoin transactions. It contains a swiss army knife of handy Bitcoin tools that support a wide range of usage models, including a few very secure ones which would otherwise be difficult to perform. The system boots into one of the three available modes: "cold-offline" - for creating a wallet and signing transactions; "cold-online" - for watching the wallet and preparing transactions; "hot-online" - standard usage but less secure as the private keys are known to the computer which is connected to the internet.

The genesis block is the first block of a blockchain, a cryptocurrency's ledger of transactions. It is assigned the value of 0. The genesis block may contain a text message written by the developer of the software; for example Bitcoin's genesis block famously includes a variable called "coinbase" which reads (in encrypted form): "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks". This refers to a newspaper headline, published on the day of Bitcoin's launch, revealing Satoshi Nakamoto's indignation over the way politicians handled the financial crisis that engulfed much of the banking and financial world at the time.

Vcash developer "xCoreDev" has released an updated build of Vcash (XVC), a new wallet client of the cryptocurrency project formerly known as Vanillacoin (VLC). It is a hybrid proof-of-work/proof-of-stake coin with an unusual feature called "ZeroTime", a technology that allows a recipient to own the coins and be able to spend them immediately, even before the transaction is confirmed on the blockchain. The new version ads several new RPC methods and fixes a number of bugs: "Vcash version 0.6.0.4 has been released. The complete changelog: TCP protocol version and minimum version increment; UDP message version and minimum version increment; ListAccounts RPC method; DecodeRawTransaction RPC method; SendRawTransaction RPC method; GetAddressesByAccount RPC method; Checkpoint sync fix; CScripts loading fix; Incentive's 'Questionable Winner' blocks will be rejected at height 705000; edited ban rules; macOS release of wxVcash and daemon; Vcash Electron." Here is the full release announcement as published on the project's News page. The Vcash wallet, available for macOS and Windows, is ready for download from the project's page at GitHub (SHA256, signature): vcash-client-0.6.0.4-osx.zip (8.03), vcash-client-0.6.0.4-win64.zip (5.29MB). Linux users will need to compile their own command-line client from the source code: 0.6.0.4.tar.gz (799kB, instructions).

Vcash (XVC) is a cryptocurrency project formerly known as Vanillacoin (VLC), rebranding earlier this year into Vcash. It is a hybrid proof-of-work/proof-of-stake coin with an interesting feature called "ZeroTime", a technology that allows a recipient to own the coins and be able to spend them immediately - even before the transaction is confirmed and consolidated on the blockchain. The new release, version 0.4.9, was announced earlier today: "Vcash version 0.4.9 has been released." The brief changelog includes the following items: "Added support for HD Keychain that can be restored from a seed (this feature is disabled in configuration by default). Database can now be configured to run in-memory or memory-mapped. Bug fixes." Here is the full release announcement as published on the project's News page. The simple but efficient wallet clients is available OS X and Windows; download links: Vcash.dmg (4.20), Vcash_64.zip (6.47MB), Vcash_32.zip (4.97MB). The source code, together with instructions on how to compile it under Linux, is available from Vcash's page on GitHub.

John Connor has announced the release of Vanillacoin (VNL) 0.4.3, the latest stable version of the hybrid proof-of-work/proof-of-stake cryptocurrency's wallet client. It is a mandatory upgrade. There is only one item on the changelog that accompanies the release announcement - a switch to BLAKE-256 as the default hashing algorithm for mining the coins: "Version 0.4.3 has been released. Added BLAKE-256 as the default proof-of-work algorithm." The BLAKE hash function was one of the five finalists in the US National Institute of Standards and Technology (NIST) competition, in 2012, to develop a new hash function called SHA-3 (eventually losing to Keccak). The two main variants of BLAKE are BLAKE-256 and BLAKE-512 - they respectively work with 32-bit and 64-bit words, and produce 256-bit and 512-bit digests. Vanillacoin network's upgrade was performed yesterday (Tuesday) and all mining nodes are required to upgrade in order to continue mining. The new wallet clients for OS X and Windows can be downloaded from here: Vanillacoin.dmg (3.88MB), Vanillacoin_64.zip (3.04MB). The source code, together with instructions on how to compile it under Linux, is available from Vanillacoin's page on GitHub.
